She's charged with two counts of contributing to the neglect of a minor.

"This 9-year-old child, he was allowed to pretty much run rough shot over that entire room for a period of 15 to 20 minutes. All his actions went unnoticed," says Vicksburg Police Chief Walter Armstrong.

The parent of one of the girls, Jamie Williams, 29, says his daughter came home for about a week with injuries, including a busted lip and a bite mark on her chin.

Williams said Thursday he got upset when daycare workers couldn't give an explanation as to why his 1-year-old daughter was injured at the daycare Monday.

That's when he slapped the child he thought was responsible.

Police say it was the wrong kid, and Williams was later arrested and charged with simple assault, a misdemeanor.

"I understand why Jamie Williams would be upset. However, even if he had attacked the nine year-old he still would have been arrested and it would have been just as wrong as him attacking the six year-old," says Armstrong.

Police have interviewed the 9-year-old boy and his mother.

It's unclear if they'll face charges.

Trevillion was being held on a $2,656 bond Friday evening.

Williams' court date is set for later this month.

The Department of Human Services is also investigating the incidents and other charges could be filed.
